THE FIRST THING YOU NEED TO KNOW:
Graves Disease is caused by your out-of-control immune system. Not your Thyroid. It is just an innocent victim.
Your immune system is mistakenly producing antibodies that attack and overstimulate your Thyroid. Causing it to produce ever increasing quantities of hormones.
If you are unlucky these antibodies also attack your eyes, and you get Graves Eye Disease too.
Getting your Thyroid hormones under control is super important.
But you have to calm your out-of-control immune system to reverse Graves Disease (and stop Graves Eye Disease).
